50 MPG combined is a shocking figure for the 2024 GMC Hummer EV SUV when equipped with its aggressive MT (Mud Terrain) tires. What makes this number truly remarkable is that the Hummer EV SUV isn’t a compact hatchback, it’s a behemoth engineered for off-road domination and packing enough electric power to humble many sports cars. This is a vehicle designed for those who prioritize capability and a bold statement above all else, and its surprisingly decent fuel economy is simply a welcome bonus.

City and highway performance

The EPA estimates of 55 MPG in the city and 45 MPG on the highway highlight an interesting characteristic of electric vehicles: they often excel in city driving. Regenerative braking, capturing energy during deceleration, contributes significantly to energy efficiency in stop-and-go traffic. The Hummer EV SUV’s advanced regen system is particularly effective, allowing for near one-pedal driving and maximizing energy recapture. On the highway, where aerodynamics and rolling resistance play a greater role, the efficiency dips slightly, as expected of a large, aerodynamically challenged vehicle with mud-terrain tires. These tires, while excellent in off-road conditions, increase rolling resistance compared to standard all-season tires.

Annual fuel cost

According to EPA estimates, the 2024 GMC Hummer EV SUV MT Tires will cost approximately $1,400 per year to keep charged up. This figure is based on driving 15,000 miles annually, using a blend of city and highway driving, and factoring in national average electricity prices. However, your actual electricity costs may vary depending on your location, charging habits (level 1 vs. level 2 vs. DC fast charging), and time-of-use rates offered by your energy provider. Charging overnight during off-peak hours, for example, can significantly reduce your annual electricity expenditure. Many Hummer EV SUV owners will also have solar panels, reducing their costs even more.

Real-world expectations

While the EPA provides a standardized testing methodology, real-world fuel economy is always subject to variation. Factors such as driving style (aggressive acceleration and braking), terrain (hilly vs. flat), weather conditions (extreme temperatures can impact battery performance), and cargo weight can all influence the Hummer EV SUV’s energy consumption. Owners using the vehicle primarily for off-roading will likely see a decrease in efficiency due to the increased energy demands of navigating challenging terrain. However, even with these variables, the Hummer EV SUV’s battery capacity provides a substantial buffer, mitigating range anxiety in most situations. Remember to check HUMMER MPG across all years as well.

How it compares

Compared to other high-performance SUVs, even electric ones, the Hummer EV SUV with MT tires holds its own surprisingly well. The Rivian R1S, another electric SUV focused on off-road capability, achieves approximately 74 MPGe combined. The Tesla Model X, focused more on on-road performance, boasts around 102 MPGe combined. However, neither of these vehicles offer the same extreme off-road capability and imposing presence as the Hummer EV SUV. Traditional gasoline-powered SUVs in this size class, like the Cadillac Escalade (16 MPG combined) or the Lincoln Navigator (17 MPG combined) pale in comparison to the Hummer’s efficiency.

Tips to maximize efficiency

Use the regenerative braking system. The Hummer EV SUV’s regenerative braking system is a key component in maximizing range. Experiment with the different regen modes to find a setting that suits your driving style and allows for efficient deceleration without relying heavily on the physical brakes. This is even more important off-road.

Optimize tire pressure. Regularly check and maintain the recommended tire pressure for the MT tires, even though it hurts off-road grip slightly. Underinflated tires increase rolling resistance, leading to decreased efficiency. Proper inflation ensures optimal contact with the road surface and reduces energy waste.

Precondition the battery. During extremely hot or cold weather, precondition the battery before driving. This feature, accessible through the vehicle’s infotainment system or mobile app, warms or cools the battery to its optimal operating temperature, maximizing efficiency and extending range.

Minimize aerodynamic drag. While the Hummer EV SUV’s design is inherently not aerodynamic, avoiding unnecessary roof racks or external accessories can help reduce drag and improve fuel economy, especially at highway speeds. Keeping the vehicle clean also helps, as dirt and debris can disrupt airflow along the body.

Plan your routes strategically. When possible, plan your routes to include charging stations and avoid areas with significant elevation changes or heavy traffic congestion. This allows you to optimize your energy consumption and minimize range anxiety, particularly on longer trips. See all Gmc fuel economy data to compare the Hummer EV SUV to the rest of the lineup.
